From aafc3ce7f289e97a21e9a01a3806684f94ff5bb9 Mon Sep 17 00:00:00 2001 From: Ruifeng Wang Date: Mon, 13 Jan 2020 14:26:05 +0800 Subject: [PATCH] devtools: add path to additional shared object files Drivers librte_mempool_ring.so and librte_pmd_null.so are loaded by librte_eal.so when running testpmd. In Ubuntu Xenial, driver path is installed to RPATH on testpmd. This allows librte_eal.so to find drivers by using the RPATH. However, in Ubuntu Bionic, driver path is installed to RUNPATH instead. The RUNPATH on testpmd is not available by librte_eal.so and therefore lead to driver load failure: EAL: Detected 32 lcore(s) EAL: Detected 1 NUMA nodes EAL: librte_mempool_ring.so: cannot open shared object file: No such file or directory EAL: FATAL: Cannot init plugins EAL: Cannot init plugins Add 'drivers' into LD_LIBRARY_PATH so that testpmd can find and make use of these shared libraries.
